MX4 - at US$300 - is a new instrument plug-in application that combines several core synthesis techniques in a unified, hybrid synthesis engine. MX4 includes several additional features not previously announced, such as built-in effects, more LFOs, external audio input, a unison multiplier and parameter randomization options for creative programming.

MOTU says that built-in chorus and delay effects allow users to program, save and recall patches with these effects as part of the patch as well as independently show/hide in the effects section to conserve screen space.
